ROLLER. BEARING.

Application filed July 2,

My invention relates to roller bearings" and may be regarded as animprovement upon the construction shownin Patent No. 1,300,485, dated `vApril l5, 1919. The object of my present improvement is to Iavoid certain defects incident to the patented con- 'struction'1 and to improve and strengthen the parts through which the bearing niembers are ret-ained in the hubs, and provides for a more expeditious and desirable assemblage o ther parts of theloearing` and hub structure. My invention resides in the speciiic form and arrangement of the cooperating parts by which the above men-A tioned objects and advantages are attained,l

the essential elements thereof being more particularly pointed` out in the appended claims. i n

In the accompanyingr drawing forming part of this specificatiomlig. l is a 'central vertical section of the hub and portions of the spokes of a wheel to which my invention is applied; and Fig. 2 is an end` or ,tace view of moved. I y

The same reference characters' indicate the same parts in bothiigures of the drawing. i y e' i It will be understood that my invention same, with the dust cap reis applicablev to roller `bearings generally,v

though it is more'particularly designedfor the bearings of light vehiclesv such as childrens wagons and the like. The hub lhof the bearing` is in the present instance formed with a medium iange provided with radial sockets for the spokes 2 of the wheel, and

is provided with a cylindrical bore of such diameter as to receive they axle 3 together with a set of rollersfl arranged circumferentially around the axle. As shown, and as in my prior patent, these f rollers are 191er serial No. aaaoe.

formed with registering annular grooves arranged to receive a retaining ring 5 Outside the two opposite Aplanes in which, the

ends of the rollers or pins` lier the bore of' the hub is formed with opposite annular grooves 6 arranged to each receive a' split spring ring 7 Vwhich is sprung into it and serves to4 retain the rollers inthe hub. In-

asmuch yasthe hubs are ordinarily made of cast iron which possesses slight ductility, and is brittle land liable to ychipy and break `when hammered, this construction andy arrangement o the retaining;v members is more secure than a construction in vwhich the end 'of the hub is upset overr ar retaining washer;

it enables the hub to be cast .in a formi which `is not altered `in assembling the hub;` is

convenient to apply,'and is highly efficient in serving the purpose for `which,l it is inas showmby a-portion) of the gear of the vehicle. The hub is held on 'the axle by a flanged dust can and retaining member l() formed with a centraltubular extension 11l surrounding the end of the axle` and se-v cured theretoby a cotter pinlQ. M

y From the description'` of my invention which has .beengiven it will ybe apparent so i that the novel lconstruction described visv 'y simple and convenient to manufacture, is y strong and durable, and highly. satisfactory and eliticient'in accomplishing the ends in view. y f I I claim:` f

yA roller bearing comprising a cast metal hub formedy with auniform cylindrical bore therethrough and Ainternal annular `grooves adjacent the opposite ends of the hub, re-

silient split rings of rounded cross-section of said rollers to hold such rollers in place.
